Connecting to Ethereum (Web3.js/Ethers.js)
Learn to use JavaScript libraries like Web3.js or Ethers.js to establish connections between a web front-end and the Ethereum network.
DApps & Ethereum Connection
Welcome to connecting your DApp's front-end to the Ethereum network! Just like traditional apps need to talk to a server, decentralized applications (DApps) need a way to communicate with the blockchain.
This communication allows your DApp to read data from the blockchain, like account balances, and send transactions, like transferring tokens or calling smart contract functions.
Web3.js & Ethers.js Libraries
To bridge the gap between your web front-end (written in JavaScript) and the Ethereum blockchain, we use specialized libraries.
- Web3.js: The original JavaScript library for interacting with Ethereum. It's widely used and robust.
- Ethers.js: A more modern, lightweight, and often preferred alternative, especially for front-end development, known for its clear API.
Both libraries serve the same core purpose: to make it easy to send and receive data from Ethereum.
